Integrated metal-and-plastic molded article and method for manufacturing integrated metal-and-plastic molded article

An integrated metal-and-plastic molded article comprising:

• a metal plate having a first surface and a second surface in a thickness direction, wherein at least one metal plate recess is formed in at least one of the first surface and the second surface of the metal plate, the metal plate defining an end plate adapted to be attached to an end of a fuel call stack at the first surface:
• a first plastic portion provided on the first surface and configured to insulate the fuel cell stack and the metal plate from each other:
• a second plastic portion provided on the second surface;
• at least one connecting through-hole that extends through the metal plate in the thickness direction and opens in a bottom surface of the at least one metal plate recess that is formed in the at least one of the first surface and the second surface of the metal plate;
• and
• an intermediate plastic portion that is arranged to completely fill the at least one connecting through-hole and be continuous with the first plastic portion and the second plastic portion, wherein
• the at least one metal plate recess being coated by a material of at least one of the first plastic portion and the second plastic portion so as to only partially fill a volume of the at least one metal plate recess,
• the at least one metal plate recess includes a first recess that is provided in the first surface,
• the first recess is configured to provide a channel adapted to selectively supply fluid to and discharge fluid from the fuel cell stack through a fluid passing hole provided in the metal plate,
• the at least one connecting through-hole opens in a bottom surface of the first recess, and
• the first plastic portion is provided also on an inner wall of the first recess and is configured to insulate the fluid flowing in the channel and the fluid passing hole from the metal plate.
